IMPROVEMENT IN STEAM-ENGINE LUBRICATORS.

Specification forming part of Letters Patent No. 1165,770, dated July 20, 1875; application filed February L4, 1874.

To all whom it may concern:

Be it known that 1, MICHAEL L. WARING, of Detroit, in the county of Wayne and State of Michigan, have invented an Iinprovenientin Steam-Engine Lubricators, of which the following is a specification:

The nature of this invention relates to an improvement in that class of lubricatingcups wherein the oil or melted tallow is caused to feed by overflowing the top, of an internal stem by the introduction of water under the oil. Heretofore it has been the practice to introduce water resulting from the condensation of steamin an external pipe or condenser under steam-pressure; but the cups operated in this manner have not proved reliable or certain and uniform in action on locomotives and other engines working at high velocities.

The object of this invention is to so construct the cup and arrange the water-supply as to enable the delivery of a continuous supply of oil to the steam-chest of the engine to which it is attached, in a uniform volume, which can be regulated to the requirements of the engine; and it consists, first, in a peculiar valve and case at the top of the internal stem, for adjusting the flow of oil to the steamchest; also, in the general arrangement of the various parts, as more .fully hereinafter set forth.

Figure 1 is a sectional elevation of the lubricator. Fig. 2 is an enlarged vertical section of the valve-case at the top of the stem. Fig. 3 is a similar view of the valve.

In the drawing, A represents a cylindrical cup mounted on a hollow stem, A, which is designed to be tapped into the top of the stea m-chest, and is provided with a stopvalve, B. O is a screw-plug in the top of the cup, which is removed to till the cup with oil. 1) is a tubular stem, tapped into the cup-stem A, extending up nearly to the top of the cupbody. On its top is secured a case, E, inclosing a cylindrical cup-valve, F, which rests upon the top end of the stem D, on which it is ground to a steanrtight joint. ais an aperture in the valve, and a is a similar one in the case, on the same horizontal plane when in position. The shellF has an angular val veface, 1), formed at its upper end, against which the seat I), in the top of the case E, is in contact when the latter is screwed on the stem D. The valve terminates at the top in a square head, 0, which projects through an opening, 0, in the top of the case. hen the plug 0 is removed from the cup the valve may be rotated in its case by a socket-wrench, so as to bring the apertures a c coincident with each other, and thus allow the escape of oil into the stem D A with a full opening; or the valve may be turned to partially close the passage and reduce the flow to single drops of oil at long intervals apart. G is a flow-pipe leadingfrom the boiler which supplies steam to the engine,

being tapped into the boiler far belo w the waterline, so as to take solid water, which it delivers into the lower part of the cup, passing, however, through a valve, H, which may be adjusted to regulate the influx of water to the cup, and for this purpose is provided with a pointer or index, d, reaching over a scale on the valve-shell. The flow of'oil out of the cup is limited by the openings to a in the case E and valve F, but is governed by regulating the influx of water by the valve H, which generally needs no change in position while the cup contains oil, the stop-valr'e B being closed when the engine is not at work, so as to prevent waste of oil. As the pressure in the boiler always exceeds that in the steam-chest in a greater or lesser degree, the oil must be forced out of the cup against the steam-chest pressure. 7

In the application of lubricating-cups to the steam-chests of locomotives, where an external siphon is used to condense steam to supply water to the cup, it has been found in practice that the water would not be condensed as fast as required, andthat, in consequence, the oil would either be blown out of the cup, or the flow would stop entirely. On quick -running portable and stationary engines such cups, owing to the vibration caused by the great variations in the pressure of the steam in the steam-chest, have been found to feed the oil with such irregularity in volume as to preclude their use.

That I claim as my invention, and desire to secure by Letters Patent, is-
